Isophthalic acid CAS No. 121-91-5
Alias：RARECHEM AL BO 0036;M-PHTHALIC ACID;1,3-dicarboxybenzene;1,3-phthalicacid;m-benzenedicarboxylicacid;m-Dicarboxybenzene;1,3-BENZENEDICARBOXYLIC ACID;1,3-PHENYL DICARBOXYLIC ACID
Molecular formula：C8H6O4
Molecular weight：166.13
Structural formula：
1.Performance and use
Isophthalic acid has strong heat resistance, hydrolysis resistance and chemical resistance, can be salted, dehydrated, hydrogenated, halogenated and other reactions, the largest use is used as an intermediate in the production of unsaturated polyester resins, followed by the manufacture of polyester resins, Chemicalbook alkyd resins (the main use of paint manufacturing) and printing inks. In addition, it can also be used for reinforcing plastics and packaging, the manufacture of film colouring agents, coatings and polyester fibre dyeing modifiers and pharmaceuticals, etc., the development and utilization of broad prospects.

3. Packaging and storage
Packaging specification: 25kg/drum，which can also be determined according to user needs
During transportation, it is necessary to protect against sunlight, rain, and high temperatures.
The product should be stored in a cool, dark, ventilated place, away from sources of fire.
4. Safety protection
Pay attention to labor protection when handling it and avoid contact with skin, eyes, etc.
After contact, rinse immediately with plenty of water
